摘要
将接触区域的法向非嵌入条件及切向连续性条件作为惩罚项引进系统的总势能泛函 ,由最小势能原理 ,得出了求解有间隙带摩擦弹性接触问题罚有限元法的公式系统 .
The no-interpenetration condition on the normal and the continuity condition on tangent being treated as the penalty terms are introduced into the totalpotential energy. Then, from the theorem of minimum potential energy, the formula system of soluing elastic contact problems with friction and initial gaps by means of penalty FEM is obtained. Examples are given to demonstrate the correctness and effectiveness of the method.
